语篇训练卷(十)Unit 4 Warming Up & ReadingⅠ. 阅读理解AThe earth is the only planet that scientists thinkhas life. Why does the earth have life while the otherplanetsdon’ t? For one thing, the earth is just the righttemperature. As the third planet from the sun, theearth seems to be just the right distance away. The planets which are closer to the sun are so hot that their surfaces bake(烘烤)in the sun. The farthest planets are cold balls.When the earth developed—which scientists believe may have happened about 4 billion years ago—many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.Only one other planet in the solar system seems to be something like the earth. That planet is Mars(火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit, you could walk around on Mars. You would have to bring your own air to breathe, because the air on Mars is too thin to breathe.Mars has the largest volcano(火山)in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected(未预料到的)sight on Mars is dried-up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.1. Which of the following is NOT the reason that the earth has life?A. The earth is just the right temperature.B. The volcanos on the earth are lower than those on Mars.C. There is oxygen in the atmosphere of the earth.D. The earth seems to be just the right distance away from the sun.2. The underlined phrase “the third planet” in the first paragraph refers to.A. the SunB. the MoonC. the EarthD. the Mars3. Which of the following about the Mars is NOT true?A. There could have been living things on Mars.B. Mars has the largest volcano in the solar system.C. There is almost no oxygen in the air on Mars.D. Mars is smaller than the earth, and it is quite a bit cooler.4. Which of the following is probably the best title for the passage?A. The EarthB. The MoonC. Planets in the Solar SystemD. Mars is Most Like the EarthBWhen Gretchen Baxter gets home from work as a NewYork City book editor, she checks her Blackberry at the door.“I think we are attached to these devices in a way that is notalways positive, ”says Baxter, who’d rather focus at homeon her husband and 12-year-old daughter. “It’s there and it beckons(召唤). That’s human nature(but). . . we kind of get crazy sometimes and we don’t know where it should stop. ”Americans are connected at unprecedented(前所未有的)levels—93% now use cell phones or wireless devices; one third of those are “smart phones” that allow users to browse the Web and check e-mail, among other things. The benefits are obvious: checking messages on the road, staying in touch with friends and family, efficiently using time once spent waiting around. The downside: often, we’re effectively disconnecting from those in the same room.That’s why, despite all the technology that makes communicating easier than ever, we stopped talking to one another. From texting at dinner to posting on Facebook from work or checking e-mail while on a date, the connectivity revolutionis creating a lot of divided attention, not to mention social anxiety. Many analysts say it’s time to step back and reassess(再评价).“What we’re going to see in the future is new opportunities for people to be plugged in and connected like ever before, ”says Scott Campbell. “It ca n be a good thing, but I also see new ways the traditional social construction is getting somewhat torn apart. ”Our days are filled with beeps and pings—many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions(干扰)are too much, but we can’t seem to stop posting, texting or surfing. “We’re going through a period of adjustment and rebalancing, ”says Sherry Turkle and she wants to remind people that technology can be turned off. “Our human purposes are to r eally have connections with people, ”she says. “We have to reclaim it. It’s not going to take place by itself. ”5. According to Paragraph 1, Gretchen Baxter thinks.A. the new technology always influences people’s life in a positive wayB. the new tec hnology always influences people’s life in a negative wayC. the family isn’t that important compared to the new technologyD. people are too dependent on the new technology to let go6. The underlined word “downside” in Paragraph 2 probably means.A. advantageB. weaknessC. strengthD. effect7. Which of the following is TRUE according to the passage?A. The wide use of mobile devices has nothing to do with the traditional socialconstruction.B. Mobile devices play a less important part in American life.C. Mobile devices create a lot of divided attention and social anxiety.D. Many analysts speak highly of the wide popularity of mobile devices.8. What can be inferred from the last paragraph?A. Something must be done to get connection with people in reality again.B. Using mobile services can help people get connection with each other.C. Mobile services have a strong impact on people’s life.D. The connection with people can happen naturally.9. What can be the best title for the passage?A. Technology Developed Quickly.B. Technology Developed Slowly.C. Technology Replaced Talking.D. Technology Made Communicating Easier.CBrian arrived at the San Francisco airport two hours beforethe flight to Paris. He was wearing three shirts, a jacket, twopairs of socks, a pair of shorts, and two pairs of jeans. He wascarrying one small backpack, which was very full, but he didn’thave any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a round-trip ticket and a small package.“Give this package to Jean Paul at the airport in Paris. He w ill have a sign withyour name on it. I think you can find him easily, ”Tony said, “You don’t have any luggage, right? ”“Only this backpack, ”Brian answered, “You said I could bring one carry-on bag. ”“That’s right. One carry-on bag is fine. Have a good trip. ”“Thanks. ”Is Brian a criminal? Not at all. He is an air-courier. And he paid only $110 for the round-trip ticket to Paris. Air-couriers get cheap airline tickets because they take important packages and papers to foreign countries. Businesses sometimes need to get packages and papers to people in foreign countries by the next day. Often, the only way they can do this is to use an air-courier company. It is not cheap for a business to send a package with an air-courier, but it is quick.Every year about 80, 000 people worldwide travel as air-couriers. The number of tickets for courier travel is growing by about 10 percent a year. However, air-courier travel isn’t for everyone. But if you have very little money, can be flexible about your travel plan s, and don’t mind wearing the same clothes for a week, it can be a great way to take a vacation!10. Why was Brian wearing so many clothes for his travel?A. Because they were the uniforms for air-couriers.B. Because that made him easier to be recognized.C. Because he would be charged for taking much luggage with him.D. Because he was required not to have much luggage with him.11. Who was Tony?A. He might be an air-courier company clerk.B. He might be a guard at the airport.C. He might be Brian’s friend.D. He might be a customs official.12. Businesses choose the air-courier service because.A. it costs lessB. it is flexibleC. it grows fastD. it saves time13. Air-courier travel is a good choice for those who.A. have much moneyB. hate wearing the same clothesC. have much personal luggageD. are flexible about their travel plans14.
